The image recognition system 1 includes a processing module 11, a sensor module 12 and a database 13. The sensor module 12 is electrically connected to the processing module 11. The database 13 is electrically connected to the processing module 11.

In the embodiment, the sensor module 12 is used for capturing images. The images are stored in the database 13. The sensor module 12 includes a first sensor group 121 and a second sensor group 122.

In the embodiment, the first sensor group 121 includes a plurality of first sensor 121A. The second sensor group 122 includes a plurality of second sensor 122A.

In the embodiment, the first sensor 121A is a charge-coupled device, i.e., the first sensor 121A is used for capturing an image showing the colors in the visible spectrum. The second sensor 122A is a thermal sensor, such as the infrared sensor, i.e., the second sensor 122A is used for capturing a thermography. In the embodiment, the sensor module 12 is used for capturing an image of a specific environment. When a user enters or occurs in the specific environment, the sensor module 12 of the image recognition system 1 captures an image of an event that the user enters the specific environment. The processing module 11 of the image recognition system 1 can use the first sensor group 121 to capture the first image shows the colors the visible spectrum. The processing module 11 of the image recognition system 1 can use the second sensor group 122 to capture the second image that is a thermography. In other words, the first sensor 121A of the first sensor group 121 is an image sensor, and the second sensor 122A of the second sensor group 122 is a thermal sensor or an infrared sensor, but being not limited in the present disclosure.

Referring to FIG. 3A, the first sensors 121A and the second sensors 122A are arrangement in a checkerboard manner. Each first sensor 121A is adjacent to the second sensors 122A.

Referring to FIG. 3B, the first sensors and the second sensors are arranged in columns.

Referring to FIG. 3C, the first sensors and the second sensors are arranged in rows.

In other embodiment, the first sensors and the second sensors can be arranged in the other manner, but is not limited in the present disclosure.

Referring to FIG. 4, FIG. 4 is a schematic diagram of a contour of the human body of an embodiment of the present.

A first contour and a second contour of the human body are respectively retrieved from the first image or the second image, and being analyzed by the processing module 11.

Even if the first contour of the human body and the second contour of the object retrieved from the first image and the second image are different, the first contour of the human body and the second contour of the object can be separated into several portions as shown in FIG. 4 according to the characters of each portion of the contour of the human body.

In the embodiment, the contour of the human body 3 includes a head portion 3A, a first hand portion 3B, a second hand portion 3C, a torso portion 3D, a first leg portion 3E and a second portion 3F.

For example, the head portion 3A is circle-shaped. The torso portion 3D is rectangular. The first hand portion 3B, the second hand portion 3C, the first leg portion 3E and the second leg portion 3F are rod-like. Even if the first hand portion 3B, the second hand portion 3C, the first leg portion 3E and the second leg portion 3F are similar, the arrangement of the torso portion 3D, the first hand portion 3B and the second hand portion 3C is different from that of the torso portion 3D, the first leg portion 3E and the second leg portion 3F.

As shown in FIG. 4, a plurality of arrangement can be found between the portions of the contour of the human body 3. For example, the head portion 3A generally is arranged above the torso portion 3D. The first leg portion 3E and the second leg portion 3F are arranged under the torso portion 3C.

Referring to FIG. 5A and FIG. 5B, FIG. 5A is a schematic diagram of the contour of the human body in a running state of an embodiment of the present disclosure. FIG. 5B is a schematic diagram of the contour of the human body in a standing state of an embodiment of the present disclosure.

Referring to FIG. 5A, the head portion 4A is arranged above the torso portion 4D, but being not in the same vertical axis. In addition, a distance is located between the first leg portion 4E and the second portion 4F. According to the above analyzing result, the state of the contour of the human body 4 can be determined to be in a running state.

As shown in FIG. 5B, the head portion 4A′ of the contour of the human body 4′ is arranged above the torso portion 4D′, which are arranged in the same vertical axis. In addition, the first leg portion 4E′ and the second leg portion 4F′ are adjacent to each other. According to the above analyzing result, the state of the contour of the human body 4′ can be determined to be in a standing state.

The processing module 11 determines the state of the contour of the human body 4 or the human body 4′ according to the arrangement of the different portions of the contour of the human body 4 or the human body 4′. In other words, the state of the contour of the human body 4 or the human body 4′ can be determined by analyzing the arrangement of the portions of the contour of the human body 4 or the human body 4′.

The arrangements of the portions of contour of the human body 4 and the human body 4′ corresponding to different states can be stored in the database 13. When the processing module 11 analyzes the arrangement of the contour of the human body and an analyzing result is obtained, the processing module 11 compares the analyzing result and the arrangement of the contour of the human body 4 or the human body 4′ to determine the state of the contour of the human body 4 or the human body 4′.

Therefore, the processing module 11 can transmit a state signal corresponding to the analyzing result of the processing module 11 to the other system. The other system can use the state signal to determine whether the human is in a dangerous state or in a stationary state, but is not limited in the present disclosure.

In addition, the number of the separation portions of the contour of the human body 4 can be varied base on the practical requirement, but being not limited in the present disclosure.

According to the above, different arrangements are located between the portions in each state. For example, when the contour of the human body 3 lay on the ground, the head portion 3A are adjacent to the torso portion 3D at the same surface. However, the arrangement between the head portion 3A and the torso portion 3D in the standing state is different from that in the lying state. Therefore, the arrangements in each state can be retrieved and pre-stored in the database 13.

Referring to FIG. 6, FIG. 6 is a flow chart of a method for recognizing images of an embodiment of the present disclosure.

The method for recognizing images in the embodiment includes the following steps: detecting whether an object is detected (Step S100); capturing at least one image by the sensor module (Step S110); separating a contour of the object retrieved from the image into several portions (Step 120); analyzing arrangements of the portions of the contour of the object retrieved from the image (Step S130); and determining a state of the contour of the object retrieved from the image based on the arrangement of the portions of the contour of the object (Step S140).

In the embodiment, the method for recognizing images can be used in the image recognition system 1 of the above embodiment. The structure and the function of the identification system are omitted in the embodiment.

In Step S100, the sensor module 12 is used for capturing an image of a specific environment. When a user enters or occurs in the specific environment, the sensor module 12 of the image recognition system 1 captures at least one image of an event that the user enters the specific environment. In other embodiment, the sensor module 12 can periodically capture the image of the specific environment, and the captured image is transmitted to the processing module 11 to be analyzed.

In Step S110, in the embodiment, the sensor module 12 includes a first sensor group 121 and a second sensor group 122. The processing module 11 of the image recognition system 1 can use the first sensor group 121 to capture the image shows the colors the visible spectrum. The processing module 11 of the image recognition system 1 can use the second sensor group 122 to capture the thermography. In other words, the first sensor 121A of the first sensor group 121 is an image sensor, and the second sensor 122A of the second sensor group 122 is a thermal sensor or an infrared sensor, but being not limited in the present disclosure.

In Step S120, a contour of the human body is retrieved from the first image captured by the first sensor group 121 or the second image captured by the second sensor group 122, and being analyzed by the processing module 11. The contours retrieved from the first image and the second image can be separated into several portions as shown in FIG. 4 according to the characters of each portion of the contour of the human body. In the embodiment, the object is a human body. In other embodiment, the object can be a cat, a dog, or other animal or a specific product, but is not limited thereto.

In addition, the number of the separation portions of the contour of the human body 4 can be varied base on the practical requirement, but is not limited thereto. In the embodiment, the contour of the human body 3 includes a head portion 3A, a first hand portion 3B, a second hand portion 3C, a torso portion 3D, a first leg portion 3E and a second leg portion 3F. For example, the head portion 3A is circle-shaped. The torso portion 3D is rectangular. The first hand portion 3B, the second hand portion 3C, the first leg portion 3E and the second leg portion 3F are rod-like.

In Step S130 and Step S140, even if the first hand portion 3B, the second hand portion 3C, the first leg portion 3E and the second leg portion 3F are similar shape, the arrangement of the torso portion 3D, the first hand portion 3B and the second hand portion 3C is different from that of the torso portion 3D, the first leg portion 3E and the second leg portion 3F. As shown in FIG. 4, a plurality of arrangement can be found between the portions of the contour of the human body 3. For example, the head portion 3A generally is arranged above the torso portion 3D. The first leg portion 3E and the second leg portion 3F are arranged under the torso portion 3D.

Referring to FIG. 5A, the head portion 4A is arranged above the torso portion 4D, but being not in the same vertical axis. In addition, a distance is located between the first leg portion 4E and the second leg portion 4F. According to the above analyzing result, the state of the contour of the human body 4 can be determined to be in a running state. As shown in FIG. 5B, the head portion 4A′ of the contour of the human body 4′ is arranged above the torso portion 4D′, which are arranged in the same vertical axis. In addition, the first leg portion 4E′ and the second leg portion 4F′ are adjacent to each other. According to the above analyzing result, the state of the contour of the human body 4′ can be determined to be in a standing state.

The processing module 11 determines the state of the contour of the human body 4 or the human body 4′ according to the arrangement of the different portions of the contour of the human body 4 or the human body 4′. In other words, the state of the contour of the human body 4 or the human body 4′ can be determined by analyzing the arrangement of the portions of the contour of the human body 4 or the human body 4′.

The arrangements of the portions of contour of the human body 4 and the human body 4′ corresponding to different states can be stored in the database 13. When the processing module 11 analyzes the arrangement of the contour of the human body and an analyzing result is obtained, the processing module 11 compares the analyzing result and the arrangement of the contour of the human body 4 or the human body 4′ to determine the state of the contour of the human body 4 or the human body 4′.

Therefore, the processing module 11 can transmit a state signal corresponding to the analyzing result of the processing module 11 to the other system. The other system can use the state signal to determine whether the human is in a dangerous state or in a stationary state, but is not limited in the present disclosure.

According to the above, the image recognition system uses at least two types of the sensors to capture different images for image recognition. In addition, the image recognition system can detect the state of the object without movement. Moreover, both of the two types of the images can be analyzed by arrangement analyzing for enhancing the accuracy of image recognition.
